China will tighten quarantine measures against the yellow fever virus, authorities said on Monday, one day after the nation's first imported case was confirmed.

Travellers from Angola, the affected region, should make themselves known to quarantine staff when entering China and show their certificates of vaccination for yellow fever, said the General Administration of Quality Supervision, Inspection and Quarantine(AQSIQ).

Measures must be taken to eliminate mosquitoes from vehicles and containers from the affected area.

A 32-year-old man from east China's Zhejiang Province experienced stage one symptoms of yellow fever, including fever and chills, on March 8 while in Luanda, capital of Angola. He sought medical treatment after returning to China on March 10 and was confirmed as the first imported case on March 13.

By Feb. 8, a total of 37 Angolans had died during the current outbreak, according to the World Health Organization.

Yellow fever is an acute viral disease transmitted by mosquitoes and mostly found in tropical regions of Africa, and Central and South America.
